15 Things You Should Never Recycle — and 10 Surprising Things You Can

February 1, 2017Brent Furdyk

We all want to take care of the environment, but are you stuffing your recycling bin with things that have no business being in there? And are you throwing away stuff that you had no idea could actually be recycled? Check out this roster of 15 things that shouldn't be placed in the recycling bin — and 10 surprising items that actually can be recycled. Note that the list of what will and won't be accepted via curbside recycling can vary widely depending upon where you — some of these items may be OK for curbside collection in your area — so it's always a good idea to check with your local district or municipality.

Don't Recycle Aerosol Cans

Don't Recycle Aerosol Cans

Aerosol paint cans will be accepted in many recycling bins throughout Canada — but only if they’re completely empty. If even a tiny bit of paint remains, the cans will be considered hazardous waste, and will need to be brought to a facility that processes household hazardous waste. To ensure that any excess residue within an aerosol can is completely eliminated, hold down the nozzle and spray into an old rag until no sound can be heard, not even air. Only then is it safe to place in the bin.

Don't Recycle Batteries

Don't Recycle Batteries

A <a href="https://www.thestar.com/news/canada/2007/04/09/discarded_batteries_pose_threat_report.html">2007 report by Environment Canada</a> predicted that Canadians would throw away nearly 500 million batteries in 2010, which is a big problem, since batteries contain heavy metals that will eventually leak from corroded batteries, and then potentially leach from landfills into drinking water. So should batteries be recycled? Yes, but they shouldn’t be placed in the recycling bin; as a result, only about two per cent of batteries wind up being recycled. Batteries need to be brought to facilities that will accept old batteries, where they can be recycled into new batteries and other materials.

Don't Recycle Brightly Coloured Paper

Don't Recycle Brightly Coloured Paper

If you have brightly coloured paper, it should not be included in your curbside paper and cardboard recycling container. The reason is similar to why you should never throw a red sock into a washing machine full of white clothing: the dyes in the paper will taint the recycling process by adding unwanted colour to the new paper products being created from the old paper. Experts recommend the best thing to do with coloured paper is to compost it along with leaves and grass clippings.

Don't Recycle Pottery and Ceramics

Don't Recycle Pottery and Ceramics

Old ceramic coffee mugs, ceramic bathroom fixtures and terra cotta planting pots can be confusing items when it comes to recycling, as they’re not glass (so shouldn’t be included with glass recycling) and aren’t organic, so can’t be composted. While ceramic items are sometimes accepted by recycling facilities that accept old concrete and bricks, the best bet when getting rid of unwanted unbroken mugs and pots is to donate them to a local thrift store.

Don't Recycle Pizza Boxes

Don't Recycle Pizza Boxes

Cardboard pizza boxes are a big no-no for recycling, because of the grease that becomes absorbed in the cardboard. When paper products, including cardboard, are recycled they are mixed with water transformed into a thick slurry. Grease from pizza boxes will cause oil to form at the top of the slurry, and oils can’t be separated from paper fibres during the pulping process. Unfortunately, the best way to get rid of pizza delivery boxes is to toss them in the regular trash.

Don't Recycle Disposable Diapers

Don't Recycle Disposable Diapers

Disposable diapers seem to be a modern necessity for parents of infants, but they were not designed to be recycled, nor can they be composted. As a result, disposable diapers are taken to landfills, where they continue to pile up. A solution may be at hand, however; a British recycling facility — <a href="http://ecopreneurist.com/2011/09/13/first-knowaste-diaper-recycling-plant-opens-in-the-uk/">the first of its kind</a> — has started recycling disposable nappies, which are being transformed into such products as plastic roofing tiles.

Don't Recycle Household Chemicals

Don't Recycle Household Chemicals

Household cleaning supplies and chemicals are deemed hazardous waste, and should never be left in a recycling bin, but neither should they just be poured down the drain, as they can corrode plumbing and will eventually make their way into waterways and oceans. Throwing away these materials in the trash is also not a viable solution, as they’ll eventually leach into the earth, contaminating soil and drinking water. As a result, most Canadian municipalities have special facilities where hazardous waste can be taken and safely disposed of.

Don't Recycle Windows or Broken Glass

Don't Recycle Windows or Broken Glass

While bottles and other glass items can be recycled at curbside, this isn’t the case for windowpanes, mirrors, light bulbs or any broken glass, which typically won’t be accepted as it poses a hazard to waste handlers. Window panes, drinking glasses and mirrors are often treated with chemicals, and have a different melting point than recyclable glass bottles, so shouldn’t be left in the same bin. To properly dispose of these items, check around to see if any reuse facilities will accept old windows, and seek out any local recycling facilities that may take broken glass.

Don't Recycle Paper Towels and Napkins

Paper towels and napkins can be recycled — and, in fact, are typically made from recycled paper — but after they’ve been used these items shouldn’t be placed in the recycling bin. The reason: food particles, etc. will wind up in the recycling process and contaminate the entire batch of previously uncontaminated paper. The best bet for used paper towels and napkins is add them to the compost heap, where they organic material will eventually break down.

Can plastic shopping bags be recycled? Yes they can, but that doesn’t mean they can be placed in curbside recycling bins. These bags need to be processed an recycled in a specialized facility, and should be kept separate from other recyclable materials. However, some cities are experimenting with ways to make recycling plastic bags easier for consumers; for example, <a href="http://www.multimaterialbc.ca/announcement/londondrugs/">a pilot project in British Columbia</a> between Multi-Materials BC and retailer London Drugs is experimenting with setting up depots in stores where customers can drop off old plastic bags and packing foam for recycling.

That paper coffee cup should be able to be included with paper in the recycling bin, right? Wrong! These paper cups have a thin coating of plastic or wax, which will compromise the entire recycling system, which isn’t equipped to separate plastic from paper, which results in contamination and will ultimately result in lower-quality recycled paper.

Don't Recycle Shredded Paper

Don't Recycle Shredded Paper

While shredded paper can be included in recycling bins in many Canadian municipalities, running paper through a shredder shortens its fibres and makes it less desirable for recycling. In addition, if you run an old credit card through a shredder and it winds up getting mixed in with other recycled paper, the plastic could wreak havoc on recycling machines. If you need to ensure confidential documents stay that way and MUST be shredded, there are companies throughout North America that will dispose of shredded paper at a reasonably low cost.

In fact, various cities are offering easier options for styrofoam recycling, such as <a href="http://www.homeforfoam.com/foam-recycling-spreads-across-canada" target="_blank">Montreal's pilot project</a> that could eventually extend to curbside recycling.

Don't Recycle Wet Paper

Don't Recycle Wet Paper

If dry paper can be recycled — mixed with water to create a slurry of paper pulp — one would assume wet paper shouldn’t be a problem. Unfortunately that isn’t the case; wet paper is extremely problematic for recyclers, as moisture harms the paper fibres, making them brittle and unsuitable for recycling. That’s why wet paper should never be placed in recycling bins — although it can easily be composted.

However, many dry cleaners and thrift stores will accept old hangers for reuse.
